Abstract

Laundry treatment composition comprising a substituted polysaccharide having a degree of substitution, DS, of from 0.01 to 0.99 and a specific degree of blockiness, DB, such that either DS+DB is of at least 1 or DB+2DS−DS² is of at least 1.20, and a laundry adjunct ingredient.

Claims

1. A composition being a laundry treatment composition or component thereof, comprising:

a substituted polysaccharide having a degree of substitution, DS, of from 0.01 to 0.99 and a degree of blockiness, DB, such that either DS+DB is of at least 1.00 or DB+2DS−

DS² is of at least 1.20 and

a laundry adjunct ingredient.

2. A composition according to claim 1, wherein the substituted polysaccharide has a degree of substitution, DS, of at least 0.55.

3. A composition according to claim 2, wherein the substituted polysaccharide has a degree of blockiness, DB, of at least 0.35.

4. A laundry composition according to claim 1, wherein the substituted polysaccharide has a DS+DB, of from 1.05 to 2.00.

5. A composition according to claim 3, wherein the substituted polysaccharide is a xyloglucan.

6. A composition according to claim 2, wherein the substituted polysaccharide is galactomannan or glucomannan.

7. A composition according to claim 2, wherein the substituted polysaccharide is chosen from a homoxylan, an (arabino)glucuroxylan, a (glucurono)arabinoxylan, or an arabinoxylan.

8. A composition according to claim 2, wherein the substituted polysaccharide is a starch.

9. A composition according to claim 3, wherein the substituted polysaccharide has a 2% by weight viscosity in water of at least 100 mPa·

s according to the viscosity test “

test method 3”

as defined in the specification.

10. A composition according to claim 3, wherein the substituted polysaccharide comprises at least one sugar unit of its backbone which is substituted with a substituent selected from the group consisting of branched, linear or cyclic, substituted or not substituted, saturated or unsaturated alkyl, amine (primary, secondary, tertiary), ammonium salt, amide, urethane, alcohol, carboxylic acid, tosylate, sulfonate, sulfate, nitrate, phosphate, silicone and mixtures thereof.

11. A composition according to claim 1, wherein the composition further comprise an enzyme having endo-β

-1,4-glucanase activity.

12. A composition according to claim 2, comprising at least 1% of substituted polysaccharide.

13. A composition according to claim 1, comprising less than 15% or 10%, for example less than 5% of phosphate builder and/or silicate builder and/or zeolite builder.
